He doesn't love the woman, you can sense it in the writing. Probably doesn't even like her that much. I picture a scenario where he drifts toward his man-cave aka start-up, when domesticity comes calling. Michael Lewis wrote a book about his domestic situation, but one never doubts he puts wife and kids first. That said, he and the wife were a little more conventinal given their approach.
I won't comment on the love angle, other than to comment that our current notion of love is a 19th century European invention that doesn't really exist in most traditional societies. There's ways of getting along that don't involve long courtship, touching poems, or passionate romance.
And it's funny you mention Lewis. The mother gave me that book as a present last March. Great book. I should note, he didn't particularly love his children at all at first...until the child was stricken ill and he had to care for him.
Our "current notion" of love may certainly change, but the neurophysiological fact of love does not (at least, not on the same timescale). I don't know what the original commenter was referring to when he said love, but I rather think he meant the emotional connection, not poetry (who think that has anything to do with love nowadays anyway?)
Love has many meanings, yes. If love is a stretch for you (or does not come naturally) at least try your best to respect their mother, treat her kindly, speak well of her, support her the best you can, and encourage her. These simple steps will do more for a child than you might realize - I don't care what the media says, parenting is really a team effort.
95% of the people I have gone on first dates with would have made disastrous life partners. It's kind of a lot to ask of him.
